Linux When it comes to the fast-moving business of trading stocks, bonds and derivatives, the world's financial exchanges are finding an ally in Linux. As late as 2007, Wall Street exchanges were still largely run on Unix . . . Over the past few years however, Linux has crept into this market, showing up first in ancillary systems and then running a few core exchanges.

"My real experiences of Solaris was 10 years ago and people called it Slowlaris so I don't really know.

I think that was the same time that Solaris wasn't very compatible with many open source software because it used a lot of the BSD-/non-GNU-tooling.

So it wasn't very attractive, at least not to me.

The reason it was called Slowlaris was because of its slow TCP/IP stack. It has now been rewritten and is called FireEngine. In older benchmarks I found, Solaris gives 30% more TCP/IP performance than Linux - on same hardware.
Slowlaris was the name given to Solaris x86 in the '90s and it was very slow - if you could get it to install. As for Fire Engine, it was 1/3 faster compared to RHEL 3.0 - that was SEVEN years ago.
Since neither OS has stood still, more recent comparisons of performance and scalability are needed.
